What is the last thing that you have learned?

They say a day when you haven't learned anything is wasted...
Did you learn anything today?
If not what is the last thing you have learned?
I have learned that lime water is potentially a great carbone dioxide absorbant...how is that?-)

That is quite interesting about the lime water. That something new which I have learned to-day. I have also learned how to use my new keyboard with shortcuts...well not all of them. I am making so many mistakes so I am still learning.
